  • Patent number: 8647511
    Abstract: Disclosed is a method for recovering a corrosion preventive agent in an electrodischarge machining liquid supply apparatus. The method includes the step of passing a first electrodischarge machining liquid having a corrosion preventive agent added there to through, an ion exchange resin column to maintain a suitable specific resistance of the first liquid, and the step of passing a second liquid free from a corrosion preventive agent through the ion exchange resin column to desorb the corrosion preventive agent adsorbed in the ion exchange resin column. The second liquid is, for example, tap water or a machining liquid having a low corrosion preventive agent concentration. The corrosion preventive agent is, for example, adenine which is a purine base.

    Abstract: A false contour reduction device reduces the occurrence of false contours on a display screen. The false contour reduction device includes a false contour occurrence pixel detection circuit, a specific color pixel detection circuit, and a false contour reduction processing circuit. The false contour occurrence pixel detection circuit detect at which pixels false contours will occur among the pixels in an image based on the input image signal. The detected pixels are false-contour-occurring pixels. The specific color pixel detection circuit detects pixels which have a specific color within a specific color range, among the false-contour-occurring pixels. The detected pixels are specific color false-contour-occurring pixels. The false contour reduction processing circuit performs a false contour reducing process on the specific color false-contour-occurring pixels.
